The New York State Museum has posted an online exhibit featuring a newly discovered audio recording of a 1962 speech by Dr. Martin Luther King Jr.

Museum officials say it's the only known recording of King's 26-minute speech commemorating the 100th anniversary of the Emancipation Proclamation at the Park-Sheraton Hotel in Manhattan. In gratitude for the speech, Gov. Nelson Rockefeller donated money to help rebuild African American churches that had been burned down in Georgia.
